176 Dr Graham's Description ofNeiv or Rare Plants. 



plants raised from seeds received from him last year ; and while I was 

 in the act of writing the description, I received information of his ha- 

 ving arrived in Edinburgh from his last successful survey of the shores 

 of the Arctic Sea. 



Salpiglossis atro-purpurea. 



S. atro-purpurea ,• foliis lanceolato-ellipticis, convexis, sinuatis, superiori- 



bus integerrimis, linearibus ; stylo edentulo. 

 Description — Stem herbaceous, procumbent for a little way at the base, 

 afterwards erect, 2 feet high, somewhat flexuose, branching. Branches 

 ascending. Leaves scattered, varying considerably in shape, the larger 

 (3-4 inches long, 1^-1 1 broad) lanceolato-elliptical, often nearly ellipti- 

 cal or ovato-elliptical, flaccid, and folded back from the middle rib, si- 

 nuated, the segments generally blunt and entire, sometimes sharp and 

 occasionally toothed on their sides, decurrent along the petiole, which is 

 nearly equal in length to the leaf; upper leaves lanceolato-linear and 

 entire, and on the flowering branches passing into linear hractece. Flowers 

 on loose terminal panicles^ Pedicels opposite to, or alternate with, the 

 bractese, stout, slightly curved upwards, as well as the stem and branches, 

 cylindrical. Calyx persisting, oblong-ovate, 5.cleft, segments acute, 

 5-angled, angles deep green, the intervening spaces paler and rugose. 

 Corolla large, inserted into the receptacle, veined, rich deep purple with- 

 in, more lurid on the outside, funnel-shaped ; tube cylindrical, twice the 

 length of the calyx ; throat much inflated, a little more on its lower side, 

 and half as long again as the tube ; limb spreading, 5.cleft, segments ob- 

 cordate, the largest above, the two smallest below ; stamens four didyna- 

 mous, with the slender rudiment of a fifth between the two longer, in- 

 serted into the orifice of. the tube of the corolla ; filaments slightly flat- 

 tened, purple towards the anthers, paler below ; anthers very large, yel- 

 low, ovate, bi-lobular, bifid at the base, the outer lobe always the largest ; 

 pollen yellow. Germen conical, channelled on both sides, bilocular, green ; 

 style single, terminal, slender below, transversely flattened and much ex- 

 panded above, without lateral teeth, pale green, longer than the fila- 

 ments, included; stigma truncated, cleft along its extremity, green. The 

 stem, branches, leaves, pedicels, and calyx, are covered with a soft, glan- 

 dular, glutinous pubescence, which appears more sparingly on the out- 

 side of the corolla, and on the filaments. When fading, the upper part 

 of the corolla is nearly deliquescent, the decay beginning in round trans- 

 parent spots, the lower part is somewhat marcescent. 

 It is impossible to suppose this the same species with the S. straminea of 

 Hooker, Ex. Fl. t. 229. ; yet as the leaves probably vary, it may not be 

 easy to find good specific characters. It seems a larger and more robust 

 plant, the branches and pedicels being considerably stouter and more 

 straight, and the stamens inserted higher in the tube. It first flowered 

 in the greenhouse of Mr Neill, Canonmills, Edinburgh, from seeds sent, 

 by Dr Gillies from hills fifty miles beyond Mendoza. Both the species 

 have flowered freely in the stove of the Royal Botanic Garden, Edin^ 

 burgh, in September and October, the seeds having been sent from the 

 f Cordillera by Mr Cruckshanks in 182G. Both differ from the Salpiglossis 

 figured by Ruiz and Pavon, Prodr. Fl. Peru v. et Chil. t. 19. in the seg- 

 ments of the corolla being larger, more spreading, and obcordate rather 

 than emarginate, and in the absence of teeth on the style* Our speci- 

 mens of -S*. straminea have the tube of the corolla as long as in the S. atro- 

 purpureay which is considerably longer than in Dr Hooker's figure; and 

 in this respect both agree with the figure of Ruiz and Pavon. 



Verbena barbata. 



V. barbata ; caule sufTruticoso, erecto, tetragono, angulis barbatis ; foliis 

 petiolatis, cordato-ovatis, acutis, crenato-serratis, utrinque pubescenti- 

 bus ; spicis terminalibus, strictis, gracilibus.
